Science

The earthquakes provided many challenges for our science and research community. Researchers worked tirelessly to understand what was happening beneath our feet and to provide support to the people who were affected by the earthquakes. Here is what we have to share.

Ground surface subsidence

The 2010-2011 Canterbury Earthquake Sequence caused regional tectonic subsidence and uplift. The earthquakes also triggered widespread liquefaction, contributing to subsidence and localised lateral sp...

Liquefaction-related land damage

The Canterbury Earthquake Sequence of 2010-2011 triggered widespread liquefaction and land damage throughout the region.   Land damage varied across the region with severity influenced by two main fa...

Localised ground surface changes

Liquefaction of underlying soil layers can cause slumping of elevated areas displacing the liquefied soils sideways. In addition to the liquefaction related subsidence, this slumping increases the ris...

Paleoliquefaction

Paleoliquefaction is the preserved evidence of liquefaction in the soil profile attributed to seismic events occurring before earthquake records began.   Following the 2010-2011 Canterbury Earthquake...
